Necrosis of human tissue can typically be obtained by exposure to temperatures below 40°C or above +50°C. However, inherent variability in tissue properties, the complexity of tissue response and dissipation of thermal energy by local perfusion or blood flow can make the development of ... Read More
Solenoid valves control fluid flow by using the passage of an electric current to produce a magnetic field that controls the displacement of a pre-tensioned plunger. As the electric current increases, the induced force causes the plunger to move upward against the force exerted by a ... Read More
A prominent technological goal at the National High Magnetic Field Laboratory (NHMFL) involves developing high temperature superconductors (HTS) for use in nuclear magnetic resonance (NMR) at fields above 31 T. Work presented here demonstrates the extensive use of finite element ... Read More
In optogenetics research it is highly desirable to have a method that can deliver light and excite individual neurons in the brain in a controllable and single cell manner. Working toward this goal, we are developing liquid microlenses with active electronics that enable both focusing ... Read More
A finite element model for underground corrosion is presented. The model is capable of predicting regions experiencing high levels of corrosion due to differential aeration and helps identify "corrosion hotspots" where physical examination of the buried asset is not feasible. ... Read More
The paper illustrates the use of the COMSOL Multiphysics® software (via the “Coefficient-Form PDE” option) for obtaining the relativistic quantum mechanics wave function ψm(x,y,ω), m=1,4 as a solution to the time independent Dirac equations. Once having ψm(x,y,ω), it can be used to ... Read More
Acoustic streaming (AS) describes a physical phenomenon where an oscillating sound emitter induces a steady fluid motion. Metal processing industry applies this treatment for grain morphology adjustments during the solidification of metal. Improvement and further development of this ... Read More
Standard approaches to reproduce the coupling of wave propagation and plasma transport inside a helicon plasma source rely on electromagnetic simulations coupled to either kinetic or particle-in-cell strategies to reproduce the plasma response. If the plasma density reach values higher ... Read More
Modern gas turbine systems for power generation are prone develop so-called thermosacoustic instabilities in the combustion chamber. Physically, these instabilities emerge as large amplitude pressure oscillations within the combustor, which are caused by constructive feedback ... Read More
A laboratory-scale electrolysis cell for the recovery of metals is simulated with COMSOL Multiphysics® software. Two models are implemented: an electrical model simulating the current density (reaction rate) distribution at the electrodes and a laminar bubbly flow model which solves for ... Read More
